Three identical metallic conducting spheres carry the following charges: q = +3.8 μC, q = −2.6 μC, and q = −8.8 μC. The spheres

Kitty [74]

Answer:

-4.1μC is the final charge on the third sphere

Explanation:

From the given data, q1 and q2 are brought into contact as they are both conductors, as such there will be evenly distribution of charges.

a) charge on each sphere(Q) = q1 + q2 / 2

= +3.8 μC + (- 2.6 μC) / 2 = 1.2μC/2 = 0.6μC

b) Now, one of those two spheres is brought into contact with the third sphere ; Q is brought into contact with q3 = Q + q3 / 2

= 0.6μC - 8.8 μC /2 = -8.2 μC/2

= -4.1μC is the final charge on the third sphere.

A jogger runs 10.0 blocks do east, 5.0 blocks due South, and another two. Zero blocks do east. Assume all blocks are equal size,

Annette [7]

Jogger moves in three displacements

d1 = 10 blocks East

d2 = 5 blocks South

d3 = 2 blocks East

now we can say

total displacement towards East direction will be

$d_x = 10 + 2= 12 blocks$

Total displacement towards South

$d_y = 5 block$

now to find the net displacement we can use vector addition

$d = \sqrt{d_x^2 + d_y^2}$

$d = \sqrt{12^2 + 5^2}$

$d = 13 blocks$

<em>so magnitude of net displacement will be equal to 13 blocks</em>
